2. 1. The Gut Bacterial Flora - Focus on Early Life and Physiological Traits

   Author : Caroline Linninge; Avdelningen för livsmedel och läkemedel; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gut microbiota; atopic eczema; inflammation; bacterial diversity; Escherichia coli; Lactobacillus plantarum; molecular-genetic methods;

   Abstract : The gastrointestinal tract of the foetus is considered sterile but during vaginal birth the neonate comes into contact with bacteria from the maternal vaginal and intestinal microbiota. The main focus of this doctoral thesis was to elucidate the initial bacterial ecosystem in newborns and to relate microbial perturbations to physiological traits. READ MORE

4. 2. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

   Author : Moorix Mo-Wai Yeung; Sten Hammarström; Marie-Louise Hammarström; Marita Troye-Blomberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestine; ulcerative colitis; lymphoid aggregates; intraepithelial lymphocytes; lamina propria lymphocytes; γδT-cells; cytokines; IL-2; carcinoembryonic antigen; biliary glycoprotein; epithelial cells; glycocalyx;

   Abstract : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. READ MORE

5. 3. Immunological tolerance to antigens in the intestine

   Author : Malin Karlsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rat; oral tolerance; serum factor; normal gut flora; exosomes;

   Abstract : The major part of the immune system is found in the epithelium and lamina propria of the gut. The distribution of the leukocytes is structured probably because the immune system has to distinguish between harmful microorganisms, food antigens and the normal gut flora. READ MORE

6. 4. The functional impact of gut microbiota on CNS regulation of local and systemic homeostasis

   Author : Afrouz Abbaspour; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The “gut microbiota” is widely accepted as an integral part of the gut homeostasis, and is thought to contribute to the establishment of intestinal barrier. Growing body of research suggest that the influence of gut microbiota on host development and physiology reaches beyond the gastrointestinal tract, and the brain is not an exception. READ MORE

7. 5. Infections Related to the Use of Medical Devices and Changes in the Oropharyngeal Flora

   Author : Hulda Thorarinsdottir; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombosis; critical illness; biofilm; intratracheal intubation; ventilator-associated pneumonia; ; central venous catheters; catheter-related infections; proton pump inhibitors; oropharynx; MICROBIOTA; foreign-body reaction; hemolysis; inflammation;

   Abstract : Background: Humans exist in mutualistic balance with a large range of microbiota. Illness and hospitalization can disturb this balance and contribute to hospital-acquired infections (HAIs), which occur most often in critically ill patients. READ MORE
